[mu] > 0 denotes viscosity coefficient, [kappa] > 0 is the Weber number and [lambda] > 0 is the
Debye length. The unknown functions are the density n, the velocity u and the electrostatic potential [PHI], respectively.
tan[([phi]).sub.max] = [square root of [delta]]/2 at [[tau].sub.2] = [[tau].sub.1] [square root of [delta]] (2) The
Debye length [[lamabda].sub.D] is calculated as the ratio of a sample thickness, d with the dimension-less, [delta]:
For solar studies, the radar wavelength must be longer than the
Debye length, a characteristic length scale in a plasma.
Table 1 shows the calculated values of
Debye length ([[lambda].sub.D]), plasma frequency ([f.sub.p]) and Debye number ([N.sub.d]) for DC discharge in argon gas at the three regions with different applied voltage.
Ionic strength (I) of the buffer solution determines an important parameter, the
Debye length the length in which mobile charge carriers screen out the external electric field, causing small charge movement (Fig.
The
Debye length of the colloidal systems ranging from 4.48 to 8.20 nm is plotted in Figure 2(d).
In a plasma, it is well known that a given charge is shielded by the surrounding ones, so that at a certain distance called the
Debye length, the charge has no effect.
where k = [([OMEGA][[lambda].sup.2]/[mu]).sup.1/2] is a normalized parameter expressed as a function of the
Debye length ([lambda]), the electric field excitation frequency ([OMEGA]), and the kinematic viscosity ([mu]).
